CANopen Conformance Test

The growing CANopen market is shared by more and more manufacturers of CANopen devices. All of them implemented a software covering the communication services provided by CANopen. To guarantee conformance of the implementations to the CANopen specification as base for correct functionality and possible interoperability of CANopen devices a standardized test procedure is defined. All current products that have passed the test and received an official certificate can be found here soon.

The CANopen devices are tested with respect to the CANopen specification version 3.0 or version 4.01, and later. The test description includes a static test where timing requirements are not taken into consideration. For every test a test report will be generated listing all steps of the test and all errors that have occured during the test.

In a first step the EDS of the CANopen device is tested. By means of an EDS a CANopen device can be described with respect to the contents of its object dictionary. The following requirements shall be fullfilled by the contents of the EDS:

• correct value ranges,
• support of mandatory entries,
• references pointing to existing entries, and
• consistancy of the EDS.

In a second step the physical CANopen device is tested. This part includes:

• the test of the application layer services,
• the test of the EDS against the object dictionary of the CANopen device, and
• the verification of the network states and transitions.

The CANopen Conformance Test Suite is available for purchase.

Conformance device certification

CAN in Automation offers the service of an official test laboratory where CANopen devices can be certified. Please contact CiA headquarters for arranging a date for the test.

The certificate describes the versions of the CANopen implementation and the EDS file. One certificate can be given for a number of devices.

The rules and regulations for testing CANopen devices can be found here.
